Their first headlining concert performance on Thursday at the Arts Garage, a benefit show in which the 150-seat venue in downtown Delray Beach is donating all proceeds to the 20-year-old brothers (stage name: Double Trouble), has sold out. But the Arts Garage has just added a second opportunity to witness their engaging rearrangements of new and nostalgic R&B hits and gospel music at 7 p.m. Sunday.

Tickets for Sunday's show are $20 (general admission), $25 (reserved), $30 (premium seating), $135 (reserved seating for six) and $150 (premium seating for six). Once again, all proceeds to go help the brothers get back on their feet.

The Arts Garage is at 180 NE First St., Delray Beach. Info: 561-450-6357 or ArtsGarage.org.
